Method for foaming of refrigerator cabinet with uniform density by feedback control and foaming system used thereof

Abstract

A method for forming foam within a refrigerator cabinet by feedback controlling and a foaming system used for the method are provided to form blowing foam with uniform density. Allowable range of each of parameters, which critically affect the blowing foam quality of the refrigerator cabinet, allowing formation of the blowing foam with the uniform density within the refrigerator cabinet is obtained through experimentation and set in advance, and before forming the blowing foam within the refrigerator cabinet, each parameters are measured to check whether a measured value is within the allowable range. If the measured value does not come within the allowable range, it is controlled to come within the allowable range by using the controlling unit and then the blowing foam is filled and formed within the refrigerator cabinet. By doing that, the reliable blowing foam with high quality and uniform density can be formed.
